Add production dependencies & build

* If the user does not specify the `arch` input, default to `${{ runner.arch }}` (instead of defaulting to `x64`)

* Add a CI workflow that tests the default arch (i.e. tests what happens when the user does not specify the `arch` input)

 Internally the action uses node's semver package to resolve version ranges. Its [documentation](https://github.com/npm/node-semver#advanced-range-syntax) contains more details on the version range syntax.
